TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4888 SUBJECT: GRB060319: MASTER optical observation DATE: 06/03/19 02:35:21 GMT FROM: Vladimir Lipunov at Moscow State U/Krylov Obs V. Lipunov, V.Kornilov, D.Kuvshinov, N.Tyurina, A.Belinski, E.Gorbovskoy, A.Krylov, G.Borisov, A.Sankovich, M.Sinitsin, P.Gritsyk, S.Korobkin Sternberg Astronomical Institute, Moscow Union 'Optic' MASTER robotic system (http://observ.pereplet.ru) responded to GRB060319.0 (GRB_TIME is 2006-03-19 00:55:42.92) by all cameras. The first unfiltred image was at 2006-03-19 00:58:24.96 UT, 80 s after notice time and 162 after the GRB time The first spectral image was at 2006-03-19 00:58:33 UT, 88 s after notice time and 170 after the GRB time The unfiltered image is calibrated relative to USNO A2.0 (0.8 R + 0.2 B). The robot not find OT-candidate in error box brighter then 17.7 (s/n=3). The reduction is continuing. This work is supported by RFFI 04-02-16411 grant. This message can be cited.
